UCF中的管教约束如下：
Net led_control_0_led_pin<0> LOC =  R20;
Net led_control_0_led_pin<0> IOSTANDARD = LVCMOS33;
Net led_control_0_led_pin<1> LOC =  T19;
Net led_control_0_led_pin<1> IOSTANDARD = LVCMOS33;
Net led_control_0_led_pin<2> LOC =  U20;
Net led_control_0_led_pin<2> IOSTANDARD = LVCMOS33;
Net led_control_0_led_pin<3> LOC =  U19;
Net led_control_0_led_pin<3> IOSTANDARD = LVCMOS33;
Net led_control_0_led_pin<4> LOC =  V19;
Net led_control_0_led_pin<4> IOSTANDARD = LVCMOS33;
Net led_control_0_led_pin<5> LOC =  V20;
Net led_control_0_led_pin<5> IOSTANDARD = LVCMOS33;
Net led_control_0_led_pin<6> LOC =  Y22;
Net led_control_0_led_pin<6> IOSTANDARD = LVCMOS33;
Net led_control_0_led_pin<7> LOC =  W21;
Net led_control_0_led_pin<7> IOSTANDARD = LVCMOS33;
mhs文件中的定制ip部分如下：
BEGIN led_control
PARAMETER INSTANCE = led_control_0
PARAMETER HW_VER = 1.00.a
PARAMETER C_BASEADDR = 0x84418000
PARAMETER C_HIGHADDR = 0x8441ffff
BUS_INTERFACE SPLB = plb_v46_0
PORT led = led_control_0_led
END
xparameters.h文件中的自制ip部分如下：
/* Definitions for driver LED_CONTROL */
#define XPAR_LED_CONTROL_NUM_INSTANCES 1

/* Definitions for peripheral LED_CONTROL_0 */
#define XPAR_LED_CONTROL_0_DEVICE_ID 0
#define XPAR_LED_CONTROL_0_BASEADDR 0x84418000
#define XPAR_LED_CONTROL_0_HIGHADDR 0x8441FFFF

软件代码如下：
#include "led_control.h"
#include"xparameters.h"
#include "xio.h"
#define delay 1000000
int main(void)
{
Xuint32 value=0xffffffff ;
    Xuint32 addr= XPAR_LED_CONTROL_0_BASEADDR;
unsigned int i;
while(1)
    {
                
                         
          LED_CONTROL_mWriteSlaveReg0(addr,0 , value);
                          for (i=0; i<delay; i++);  
           
    }
   
     
     
}
